Hi,

Yes exactly. the later DSP cars have the TCU connected directly to the amplifier, rather than going through the BM like the earlier ones. Somehow the 09/2002+ E39s followed the same exact wiring schematic as the later E53s. This is why that DSP_PROFILE field in the FSW needs to be correct and mirrored from a late X5.


Thanks!
